The Long View Marathon to bieg punkt-punkt między Fort Collins a Loveland w północnym Colorado. Maraton startuje z Edora Park, a kończy się w Fairgrounds Park. Na tej samej mecie kończy się też półmaraton, który startuje z Fossil Creek Park, oraz 5K z bazą w Fairgrounds Park. Biegi są w październiku, ze startami rano, ale rozłożonymi w czasie dla maratonu, półmaratonu i 5K. Trasa wykorzystuje fragmenty ścieżek rowerowych Long View i Front Range. Czyli dłuższe dystanse biegną po utwardzonej ścieżce, a nie po zamkniętej pętli w centrum miasta. Pakiety startowe można odebrać w Altitude Running w Fort Collins przed dniem biegu oraz w strefie startu każdego biegu rano w dniu zawodów, ale trzeba pamiętać o limicie czasowym. Nagrody w maratonie i półmaratonie to indywidualne prace lokalnej artystki Amy Hayman, karty podarunkowe do lokalnych firm, nagrody generalne i w kategoriach wiekowych. W 5K są nagrody generalne i dla mastersów.

NCMC Turkey Trot startuje niedaleko North Colorado Medical Center w Greeley, Colorado, rankiem w Święto Dziękczynienia. Organizuje to CardioVascular Institute of North Colorado. Mają tam dla biegaczy i chodziarzy 5K z atestem USATF i krótszy, taki "fun run" 2K Gobler Trek. Najpierw startuje 5K, a zaraz po nim 2K. Dzięki temu rodziny mogą wybrać: albo bieg na czas, albo po prostu taką luźniejszą aktywność na święta. Start jest po wschodniej stronie North Colorado Medical Center, a meta na 16th Street, prosto przed szpitalem. Na imprezę przyjeżdżają ludzie w każdym wieku i na każdym poziomie zaawansowania. Ci, co chcą się ścigać, ustawiają się z przodu, przed tymi z wózkami czy przyczepkami. To jedna z większych imprez świątecznych w Northern Colorado, a kasa z niej idzie na programy rehabilitacji kardiologicznej i płucnej. Pomaga to finansowo pacjentom, których inaczej nie byłoby stać na rehabilitację.
